Ease of Use:


  • rechargable but without needing recharging first
    Verified BuyerReviewed by happycamper12345 - July 23, 2017

    I love having these because I get all the advantages of a rechargeable battery - but when I need one, I don't have to recharge it first / fast because it holds charge between recharging and use - not like the older rechargeables where I'd have to take it out of the drawer and then recharge it. Especially as recently I've had a few problems with my non-rechargables. This is definitely my preferred brand as they have never leaked on any of my electronics or on my other batteries unlike my non-rechargeables and they hold more power than my older rechargeables. Price isn't bad given what I am getting. Non-rechargables cheaper up front but more hassle to me lately so I'd prefer to stick to rechargables from here on out.

  • High quality rechargeable batteries
    Verified BuyerReviewed by jcps - November 3, 2017

    I purchase these because they are high quality rechargeable batteries... I use rechargeable batteries in almost everything in my home that uses batteries... Then are 1.2V batteries, where as non-rechargeable batteries are 1.5V... Thats ok, it just means they won’t last as long as regular batteries, but when you can recharge them over and over again, the savings in the long run outweigh that issue. Very happy and will continue to use them again and again!

  • Works as good as my High-Capacity Energizer AAA's
    Verified BuyerReviewed by nitroburn1972 - March 26, 2017

    Works as good as my High-Capacity Energizer AAA's. Haven't really evaluated them thoroughly, but the experience I've had with them so far has been good. None have prematurely died and they seem to work as well as my 900mAh Energizers that I've had for years. Mainly use them in remote controls and, out of habit, recharge them once a month just to keep the voltage up there near the top. Works as expected...which is a good thing. :)
